      "message": "mutex: have non-spinning mutexes on s390 by default\n\nImpact: performance regression fix for s390\n\nThe adaptive spinning mutexes will not always do what one would expect on\nvirtualized architectures like s390. Especially the cpu_relax() loop in\nmutex_spin_on_owner might hurt if the mutex holding cpu has been scheduled\naway by the hypervisor.\n\nWe would end up in a cpu_relax() loop when there is no chance that the\nstate of the mutex changes until the target cpu has been scheduled again by\nthe hypervisor.\n\nFor that reason we should change the default behaviour to no-spin on s390.\n\nWe do have an instruction which allows to yield the current cpu in favour of\na different target cpu. Also we have an instruction which allows us to figure\nout if the target cpu is physically backed.\n\nHowever we need to do some performance tests until we can come up with\na solution that will do the right thing on s390.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nLKML-Reference: \u003c20090409184834.7a0df7b2@osiris.boeblingen.de.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
